I’ve tried restarting the device a number of times (already on the test pattern) and it still gives me the same error.

Edit: Finally got it to update after putting it on a hard surface instead of carpet and leaving it unplugged for a little while.

I’ve been unable to get the update to work as well, but for me it almost immediately gives me a message saying it failed with a -9 in parenthesis.

Since the custom scaling algorithm setting allows MiSTer format scaling filters to be used, it is possible to copy scaling filters from “Upscaling – SharpBilinear” in the MiSTer’s pre-set filters, but these only define the ratio of nearest neighbor to bilinear (SharpBilinear_000.txt being pure bilinear), not the exact scaling factor for the nearest neighbor interpolation. It would be nice to have a bilinear sharp setting that works like Zacabeb described, if for nothing else than to know that it’s the correct scaling factor for the nearest neighbor phase, which is hard to guarantee with any of the MiSTer filters.

It’s worth noting also that while GS Sharp looks like sharp bilinear interpolation, it has still given me noticeable scrolling shimmer with the SNES 512×240 preset and Kirby’s Dream Land 3, so I’m not 100% willing to trust it.

That’s a bit unfortunate, but I’m reasonably confident I can figure out how to get the results I want using the MiSTer filters. Thanks for your help.

I don’t understand your question. My idea is to have the OSSC add pillarboxing, not windowboxing. As is, when the OSSC is outputs 720×480, my monitor can display that in either 3:2 or 16:9. The image needs a bit more pillarboxing than the display can add to get to 4:3. I’ve already tried buying a new monitor with proper aspect control built in three times now, and every time there’s been something wrong with it and I ended up having to return it. It’s very frustrating. Only a handful of brands offer that functionality in monitors, so there’s not a lot of options there anyways.

That makes a lot of sense of things. Tweaking advanced timing to change 720 to 704 fortunately does work with my monitor, but that does seem to require increasing horizontal backporch in order to re-center the image. Is default +8 the correct value for the backporch in that scenario?

So if I use 3x or 4x for 240p (or mess with advanced timing for 5x) and adjust horizontal active and backporch for 480i and 480p, I can get the correct aspect ratio for 240p games and widescreen 480i and 480p games, but I’m still stuck only being able to display 4:3 480i/p games as being 10% too wide, unless I get a new monitor. With a bit of research, I’ve found that Asus, Dell, Samsung, and ViewSonic make monitors that provide 4:3 distortion as an option, but a new monitor seems like a big investment over a small error. What would be more helpful is if the OSSC itself had modes for adding blank pixels to the left and right sides of a 480i or 480p signal, just like 240px3 in generic 4:3. I tried achieve something like that using advanced timing, but I didn’t have much luck. Perhaps this is something I should post about in the “feature requests” section?

One last thing that seems curious to me is that the 240p optimal modes seem to operate around a different set of ideas about how aspect ratio should be handled, at lest for a 240p source. These modes seem to be designed to completely fill a 4:3 frame (or alternatively 8:7 for 256×240), but using the 240p test suite on the Wii, I get a narrower image in 3x and 4x generic than when using 320×240 optimal. If the optimal modes mess up the intended aspect ratio, that’s a bit of a shame, considering how fantastic things look with optimized settings.
